Objective To explore the effect of enhanced recovery after surgery(ERAS)in perioperative period of complicated appendicitis in children.Methods A total of 248 children with complicated appendicitis who underwent laparoscopic surgery in Quanzhou Children's Hospital from January 2020 to January 2023 were selected and divided into control group and ERAS group according to random number table method,with 124 cases in each group.Both groups of patients underwent laparoscopic appendectomy.The control group received traditional treatment during perioperative period,while the ERAS group received treatment based on the concept of ERAS.The first postoperative exhaust/defecation time,hospital stay,visual analogue scale(VAS)score,postoperative complications and hospitalization satisfaction were compared between two groups.Results The time of first postoperative exhaust/defecation and hospital stay in ERAS group were significantly shorter than those in control group,total incidence of postoperative complications and postoperative VAS score were significantly lower than those in control group,and hospitalization satisfaction was significantly better than that in control group(P<0.05).Conclusion ERAS implementation during perioperative period of complicated appendicitis in children can promote early postoperative recovery,reduce postoperative pain,reduce the incidence of complications,and improve hospitalization satisfaction,which is worthy of clinical promotion and application.
